Since our founding in 1991, arXiv has been free to use and open to all. A pioneer of open access for close to 35 years, arXiv now hosts more than 2.6 million schol- arly articles in eight subject areas. arXiv’s community of volunteer moderators are experts in their fields who, along with our editorial team, ensure content quality while remaining ded- icated to distribution at the speed-of-science. arXiv is a repository for articles and so much more: arXiv provides an article submission portal, a TeX compilation service, search and discovery tools, web distribution for human readers, API access, machine-readable data sets, and community-developed tools to enhance user experience. Our emphasis on openness, collaboration, and scholarship — as well as the open access com- munity that supports us — provides a strong foundation for arXiv to continue to grow and thrive. 4 Mission arXiv is an open platform where researchers can share and discover new, relevant, and emerging sci- ence and establish their contribution to advancing research. Vision Our vision is for all researchers around the world to have immediate, free, and open access to estab- lished and emerging research in their field. Values arXiv is open, above all. The foundation of arXiv is based on open access, transparency, open minded- ness, collaboration, and flexibility. arXiv is a community. Our sta ! , institutional mem- bers, collaborators, moderators, authors, and readers all make arXiv possible — together, we are arXiv. arXiv is passionate about science — and access to science. Science is for everyone, and arXiv makes sure it stays that way. arXiv does more with less. To best serve research- ers and research, arXiv runs lean — everything we have goes into the work. arXiv values excellence. We meet the challenges of the future with a collective passion for our work and our community. Mission, Vision, and Values
